An Image Encryption Scheme Based on Lorenz Hyperchaotic System and RSA Algorithm

Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021
This research proposes a new image encryption scheme based on Lorenz hyperchaotic system and Rivest–Shamir–Adleman (RSA) algorithm. Firstly, the initial values of the Lorenz hyperchaotic system are generated by RSA algorithm, and the key stream is produced iteratively.

Multimedia Communication Security in 5G/6G Coverless Steganography Based on Image Text Semantic Association

Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021
Recently, researchers have shown that coverless steganography is relatively safe. On this basis, to improve the payload of the coverless steganography, a novel semiconstruction coverless steganography algorithm is introduced in the paper. Firstly, web crawler technology is applied to crawl a wide range of small icons and hot news images from the ...

A Coverless Audio Steganography Based on Generative Adversarial Networks

Electronics, 2023
Traditional audio steganography by cover modification causes changes to the cover features during the embedding of a secret, which is easy to detect with emerging neural-network steganalysis tools. To address the problem, this paper proposes a coverless audio-steganography model to conceal a secret audio.
